The book "The Greek World 479-323 BC" is an indispensable guide to classical Greek history since its first publication nearly thirty years ago. Simon Hornblower has revised and partially rewritten his original text, bringing it up to date for another generation of readers. In particular, this fourth edition fully considers recent and detailed studies regarding the Greek city-states throughout the Greek world, allowing for greater development of the central theme of regional diversity across the Mediterranean and beyond. Other extensive changes include a new subsection on the islands, a completely updated bibliography, and revised citations of epigraphic material related to the 4th century BC. With valuable coverage of the broader Mediterranean world in which Greek civilization flourished, as well as a close examination of Athens, Sparta, and the other major city-states of Greece, this fourth edition of a classic work is more essential than ever.
